Key Ingredients & Substitutions

Cooked Chicken: Shredded rotisserie chicken makes this dish super easy, as it’s already cooked. If you prefer, you can use grilled chicken breasts or any leftover chicken you have.

Spaghetti Pasta: Regular spaghetti works great, but you could also use whole wheat pasta or gluten-free pasta if needed. Just keep an eye on the cooking time, as it may vary!

Soups: The cream of mushroom and cream of chicken soups add creaminess and flavor. If you’re avoiding cream soups, you can try a mixture of plain Greek yogurt or sour cream with broth as a lighter substitute.

Cheese: Cheddar and mozzarella create a deliciously cheesy topping. Feel free to mix in Monterey Jack or even a dairy-free cheese for a different flavor or for dietary preferences.

How Do I Cook the Noodles Perfectly in the Crockpot?

Cooking pasta in a crockpot can be tricky, but here’s how to do it right. Ensure the spaghetti is broken in half and submerged in the sauce to cook evenly.

  • Mix your ingredients well to cover the noodles with sauce.
  • Keep the lid on while cooking to trap steam, which helps the noodles cook thoroughly.
  • Check the noodles around the 3-hour mark. If they’re not tender yet, give them a stir and check again in 15 minutes.

If you find that the mixture looks too dry, add a bit more chicken broth to keep everything moist!

Cover the crockpot and cook on low for 3 to 4 hours. Check for doneness at around 3 hours to see if the noodles are tender and ready!

7. Add the Cheesy Goodness:

About 15 minutes before you’re ready to eat, stir in the shredded cheddar and mozzarella cheeses. Cover the crockpot again so the cheese can melt into the sauce!

FAQ for Easy Crockpot Chicken Spaghetti

Can I Use Frozen Chicken for This Recipe?

Yes, you can! Just make sure to thaw the frozen chicken completely before adding it to the crockpot, as cooking from frozen can lead to uneven cooking. The best way to thaw is by transferring it to the fridge the night before or placing it in a sealed plastic bag submerged in cold water for a few hours.

What Can I Substitute for Cream Soups?

If you want to avoid cream soups, try using a mixture of plain Greek yogurt or sour cream combined with some chicken broth. This will still give you a creamy texture and delicious flavor without the canned option!

How Do I Store Leftovers?

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, simply warm it gently in the microwave or on the stovetop, adding a splash of broth or water if it looks too dry.

Can I Make This Recipe Gluten-Free?

Absolutely! Just swap the regular spaghetti for gluten-free pasta. Be sure to adjust the cooking time since gluten-free pasta can cook a bit differently than traditional pasta. Start checking for doneness at around the 2.5-hour mark.
